Application of BEM-FEM coupling and the vector Preisach model for the calculation of 3D magnetic fields in media with hysteresis

This paper deals with the coupling of finite elements and boundary elements far the calculation of 3D magnetic fields in media with hysteresis, For th e description of hysteresis effects the vector Preisach model is used, The numerical implementation of the 3D vector Preisach model is addressed. A bo undary value problem (bvp) with ferromagnetic material for which an analyti cal solution exists is presented. This bvp can be used to validate the nume rical approach. Numerical and analytical solution of the bvp show very good agreement.
